Answer:

Step-by-step explanation:

relation is a function if we have y for every x from domain and for one x we have one and only one y

x = 1 --> y = 2

x = 2 --> y = 2

x = -2 --> y = 2

no x-es without y-es

and no two the same x-es with one y

so this relation is a function

Answer: Option 1

Step-by-step explanation:

1. You know the lenght of both rectangular prism, therefore if both are similar, the scale factor is:

$sf=\frac{12cm}{4cm}\\sf=3$

2. Then the scale factor of the volumes is:

$sf_v=3^{3}\\sf_v=27$

3. Now, you must multiply the volume of the smalller rectangular prism by the scale factor obtained, then you obtain the following result:

$V_2=(24cm^{3})(27)=648cm^{3}$
